MemVerge provides additional instructions for some popular applications supported by Memory Machine, either to assist with complex setup or to support additional functionality.
Working with Hazelcast Clusters
You can take a snapshot of a distributed Hazelcast cluster running on Memory Machine managed hosts and later restore the cluster to its original state.

Overview and Installation
Getting started with MemVerge Memory Machine requries that you understand some background information about how persistent memory works. You can then install Memory Machine on a server and begin monitoring memory usage and capturing application snapshots.
Using the Memory Machine Dashboard
You can view system resources and performance metrics, and create and restore snapshots in MemVerge Memory Machine using the Memory Machine Dashboard, a web UI application running on one of the installed hosts.
Using the Command Line Interface
You can administer and use MemVerge Memory Machine using the Command Line Interface (CLI) on any installed host.

- Working with Hazelcast Clusters
  You can take a snapshot of a distributed Hazelcast cluster running on Memory Machine managed hosts and later restore the cluster to its original state.
  - Preparing Memory Machine to Work with Hazelcast
    To prepare for taking snapshots of the Hazelcast cluster: install Memory Machine, enable namespace restore, and provide the Hazelcast credentials to all hosts in the cluster.
  - Preparing Hazelcast to Work with Memory Machine
    To prepare Hazelcast to work with Memory Machine Cluster Snapshot you must configure Hazelcast on each host; create a user that belongs to the Memory Machine mvmm group; run Hazelcast on each host in Active state as a background process; and register the Hazelcast cluster with Memory Machine.
  - Capturing a Cluster Snapshot
    After configuring Memory Machine and Hazelcast, use the mvmcli cluster snapshot command to capture a snapshot of the cluster state.
  - Restoring a Cluster Snapshot
    Use the mvmcli cluster snaprestore command to capture a snapshot of the cluster state.
  - Deleting Cluster Snapshots
    Delete a cluster snapshot using the mvmcli cluster snapdelete command on the Primary Coordinator host.
  - The Cluster Snapshot Command
  - Troubleshooting Hazelcast Cluster Snapshot
- Working with KVM in Memory Machine
  Running KVMs in Memory Machine requires extra setup and configuration.

Working with Hazelcast Clusters

You can take a snapshot of a distributed Hazelcast cluster running on Memory Machine managed hosts and later restore the cluster to its original state.

Using MemVerge Memory Machine, you can manage the hosts of a Hazelcast cluster and capture snapshots of the cluster state. Working with Hazelcast cluster snapshots in Memory Machine involves the following tasks:

Configure Memory Machine to work with Hazelcast clusters.
Configure Hazelcast to work with Memory Machine.
Take snapshots of the entire cluster.
Later, restore the cluster to the state it had when the snapshot was taken.
Delete unwanted cluster snapshots from Memory Machine.
